There were open source projects and free software before Linux was there. Linux in many ways is one of the more visible and one of the bigger technical projects in this area, and it changed how people looked at it because Linux took both the practical and ideological approach.
Linus TorvaldsLinux has more than satisfied any small initial expectations I had. It's simply incredible how successful Linux has been, and how good a time I've had developing it and leading the project. It does take a lot of my time, but it's time I really enjoy spending, and Linux has continued to be challenging both technically and from a managing standpoint.
Linus TorvaldsYou can do a lot of things with git, and many of the rules of what you *should* do are not so much technical limitations but are about what works well when working together with other people. So git is a very powerful set of tools.
Linus TorvaldsIn science, the whole system builds on people looking at other people's results and building on top of them. In witchcraft, somebody had a small secret and guarded it - but never allowed others to really understand it and build on it. Traditional software is like witchcraft. In history, witchcraft just died out. The same will happen in software. When problems get serious enough, you can't have one person or one company guarding their secrets. You have to have everybody share in the knowledge.
